Struct swc_ecma_transforms::optimization::JsonParse

pub struct JsonParse {
    pub min_cost: usize,
}

Trnasform to optimize performance of literals.

This transform converts pure object literals like

{a: 1, b: 2}

to

JSON.parse('{"a":1, "b"}')

COnditions

If any of the conditions below is matched, pure object literal is converter to JSON.parse

• Object literal is deeply nested (threshold: )
